Description

Neutron reflectometry (NR) is an ideal technique for in-situ and in-operando investigations of the materials, thin films, and interfaces crucial to energy related systems. NR is a non-perturbing probe of the depth profile of structure in thin-film materials with sub-angstrom accuracy. Advantages include sensitivity to light elements; determination of porosity and composition by isotopic substitution (e.g., lithium, hydrogen); and capabilities for numerous precisely controlled in-situ electrochemical, thermal, liquid, gas, and other environments, as well as accessibility for various in situ stimuli and probes. We have recently applied NR to open up new opportunities in batteries by characterizing the structure of the Solid Electrolyte Interphase (SEI) layer, in-situ, in a Li-ion battery as a function of operating conditions (Owejan et al.), to illuminate potential issues at fuel cell interfaces (Dura et al.) and to investigate hydrogen storage materials. Research opportunities exist to explore these and numerous additional diverse systems for energy production, conversion, and storage as well as for more fundamental studies of electrochemistry, physics, materials and device issues, and hydrogen interactions.
